Cup anemometer 3S-WS-PLS-P

IP54compactwith pulse output

Product Overview
The 3S-WS-PLS-P plastic wind speed sensor (cup anemometer) measures horizontal wind speed and provides pulse output via a reed relay for direct integration with SCADA, PLC or data loggers. The sensor is designed for outdoor industrial and environmental applications, using UV-resistant plastics and a compact, low-maintenance mechanical design.

Standard & Monitoring Note
Compliant with IEC 61724-1:2021. Wind speed data can be used to estimate module temperatures and to support assessments of wind-related damage. To monitor gusts (typically up to 3 s), use a sampling period ≤ 5 s and record both average and peak values.

Key Features

• Plastic construction (ASA/ABS): UV-resistant materials suitable for outdoor exposure.
• Pulse output (reed relay): Provides clean digital pulses for counting or frequency measurement.
• Compact design: Small footprint and low weight for easy mounting.
• IP54 protection: Resistant to dust ingress and splashing water for outdoor use.
• Wide measurement range: 0.9–60 m/s for calm to high-wind conditions.

How It Works
The rotating cups drive a magnet that actuates a reed switch; each rotation generates a pulse. Pulse frequency is proportional to wind speed and is counted or measured by the connected monitoring system for real-time display or logging.

Benefits

• Defined measurement performance: Specified resolution and accuracy for operational monitoring and assessments.
• System compatibility: Pulse output compatible with common SCADA, PLC and data-logger inputs.
• Low maintenance: Simple mechanical design; optional heated model for icing conditions.
• Flexible deployment: Pipe or ground mounting and custom cable lengths available.

Applications

• Wind energy monitoring: Site evaluation and turbine performance tracking.
• Weather stations: Meteorological data collection for forecasting and research.
• Industrial sites: Process and safety decision support requiring wind data.
• Agricultural monitoring: Field condition assessment and spray/irrigation planning.

Installation & Maintenance
Installation: Mount at an unobstructed location at the appropriate height; use pipe or ground mounting as required. Maintenance: Low-maintenance design; periodic cleaning and inspection recommended in dusty or polluted environments and after extreme events.
